As part of the RedoxWind project, the Fraunhofer Institute for Chemical Technology (ICT) commissioned Europe’s largest vanadium redox flow battery, according to its own statements. The battery has an output of two megawatts and a capacity of 20 megawatt-hours. It is located on the Fraunhofer ICT site in Pfinztal as a pilot plant and is directly connected to the DC link of a 2-megawatt wind turbine. Fraunhofer ICT claims that a test demonstrated how renewable energies can be fed into the power grid in a targeted and predictable manner, regardless of current weather conditions. This combination of a wind turbine and a battery could provide a self-sufficient power supply for isolated locations, businesses, or villages.
The modular vanadium redox flow battery was developed and built entirely with German components and expertise. It serves as a research and development platform for testing and further developing new storage technologies and components in collaboration with German and international industry partners.
